The standard temperature range for hot tools used on hair, particularly styling tools like curling irons or flat irons, is typically between 300 to 400 degrees Fahrenheit. This range is effective for achieving desired styles while minimizing the risk of damaging the hair. Hair’s structure can withstand temperatures in this range while allowing for proper styling without excessive brittleness or breakage.

Using tools set at temperatures lower than 300 degrees may not provide the necessary heat to effectively alter hair texture or style it as intended. Conversely, settings above 400 degrees can increase the potential for significant damage, such as burning the hair or affecting its texture in a negative way. Therefore, 300 to 400 degrees Fahrenheit represents a balanced approach that provides effective styling results while maintaining the integrity of the hair.
